In simple, WD special edition gives you performance on large files
IBM 120gxp gives you performance on games, OS, small files, etc.
why? WD have the benefit of 8mb huge buffer size to hold large files. But why large files will be faster with WD? becoz the HD don't need to seek as many times as many small files. In the other hand, IBM have the ability to "seek" the file in a faster time than WD only able to hold 2mb data.
p.s. almost anythings you do with your computer require R/W data to/from the HD. every bit it R/W needed to be physically seek on the hard "disk" surface before it can actually R/W. Therefore, seek time will be extremely important for a fast harddisk operation.
just think what is your needs before buy a harddrive. if you really do a lot of video edition or other large files, get a SCSI harddisk.... EIDE is too slow for these files
not only I think like this, also........

IBM's Deskstar 120GXP is currently one of the best choices for a hard-drive upgrade, offering excellent sustained throughput and a spacious, 120GB capacity. While the equally fast Western Digital WD1200JB is the slightly better drive for audio and video storage, the Deskstar 120GXP is just as good a choice for other computing uses. (Note: In spite of the product's name, there are different 120GXP models, which vary in capacity from 40GB to 120GB.)
